Twenty individuals with chronic pain were randomly assigned to one of five doses 0.0, 0.5, 1.0, 1.5, 2.0-in milligrams (mg) of medication. The results are shown in the scatterplot below. Pain Relief (hours) 14- 12- 10- 8. + 2 0.0 0.5 1.0 Dose (mg) 1.5 2.0 The data were used to fit a least-squares regression line to predict the number of hours of pain relief for a given dose. Which of the following would be revealed by a plot of the residuals of the regression versus the dose? (A) The sum of the residuals is less than 0. (B) The sum of the residuals is greater than 0. (C) There are outliers associated with the lower doses. (D) The variation in the hours of pain relief is not the same across the doses. (E) There is a positive linear relationship between the residuals and the dose.arrow_forward

- Investing: Inverse ETFS (Exchange Traded Funds) Inverse ETFS, sometimes referred to as "bear market" or "short" funds, are designed to deliver the opposite of the performance of the index or category they track, and so can be used by traders to bet against the stock market. The following table shows the performance of three such funds as of August 5, 2015.t Year-to-Date Loss (%) MYY (ProShares Short Midcap 400) 6 SH (ProShares Short S&P 500) 5 REW (ProShares UltraShort Technology) 7 You invested a total of $6,000 in the three funds at the beginning of 2011, including an equal amount in MYY and SH. Your total year-to-date loss amounted to $360. How much did you invest in each of the three funds?

If the animal is in the meadows on one observation, then it is three times as likely to be in the meadows as the woods on the next observation.Assume that state 1 is being in the meadows and that state 2 is being in the woods.(1) Find the transition matrix for this Markov process. (2) If the animal is initially in the woods, what is the probability that it is in the woods on the next three observations? (3) If the animal is initially in the woods, what is the probability that it is in the meadow on the next three observations?arrow_forward
